I believe it's unecessary to change everything here. Only the password if that was shared. My e-mail here and there is the same, but not the password. I won't change a thing. My MangaTraders password is an old one I don't use for years now, so no worries.

Ok, i just want to ask because i don't understand it. Even if they hacked MT and got mail and passwords and so for example from me, how could they harm me? How could they find out where to use my info that they have from MT?

First, they can easily crack unsalted MD5 passwords. If that email/password combination was used on any other site, they could log into that site as you and try to do any number of things, including social engineering attacks. An end goal would be to get into the email account itself, which could cause huge amounts of problems.

lambchopsil, from the way you said that, it's obvious that the passwords here are at least salted, but now I just have to check, you guys aren't using MD5, right? I hope you're using at *least* SHA-1.... SHA-256 or so is preferred....
